Bugzilla Bug 217885

Some ebuilds talk about "qt" useflag. However, it has been renamed to "qt3".
See:

$ cd /path/to/portage/app-doc/doxygen
$ fgrep elog *.ebuild | fgrep qt
doxygen-1.4.2.ebuild:   elog "The USE flags qt3, doc, and tetex will enable
doxywizard, or"
doxygen-1.4.3-r1.ebuild:        elog "The USE flags qt3, doc, and tetex will
enable doxywizard, or"
doxygen-1.4.4.ebuild:   elog "The USE flags qt3, doc, and tetex will enable
doxywizard, or"
doxygen-1.4.5.ebuild:   elog "The USE flags qt3, doc, and tetex will enable
doxywizard, or"
doxygen-1.4.6.ebuild:   elog "The USE flags qt3, doc, and tetex will enable
doxywizard, or"
doxygen-1.4.7.ebuild:   elog "The USE flags qt, doc, and tetex will enable
doxywizard, or"
doxygen-1.5.1.ebuild:   elog "The USE flags qt, doc, and tetex will enable
doxywizard, or"
doxygen-1.5.2.ebuild:   elog "The USE flags qt, doc, and tetex will enable
doxywizard, or"
doxygen-1.5.3.ebuild:   elog "The USE flags qt, doc, and tetex will enable
doxywizard, or"
doxygen-1.5.4.ebuild:   elog "The USE flags qt, doc, and tetex will enable
doxywizard, or"
doxygen-1.5.5.ebuild:   elog "The USE flags qt, doc, and tetex will enable
doxywizard, or"

The funny thing is that most 1.4.* ebuilds are updated to qt3 (except 1.4.7),
while all 1.5.* ebuilds are not.

Fixed.
